Z-Bore Valve Systems

The Z-Bore Valve System is very similar to the Super Large Bore System. By using an O-ring seal to clamp the spud to the rim, a greater flow diameter is created without sacrificing strength or performance.

Like Super Large Bore Extensions, you can use a kit to allow extension assembly in the field. Rigid extensions are also available. Z-Bore flows 370 CFM compared to 240 CFM on the Super Large Bore Valve System.
